IMPROVED ICE-CREAM FREEZER.

TO ALL WHOM IT MAY CONCERN:

Be'it known that I, CHARLES W. PACKER, of Philadelphia, Pennsylvania, have invented certain improvements in-Ice-Cream Freezers; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improvements, fully described hereafter, in the ice-cream freezer for which Letters Patent were granted to me on the twenty-second day of May, 1860; my present improvement being such as to facilitate the removal and replacement of the several parts,and effectually scrape from the inside of the vessel the frozen cream, to make way for that which is in a fluid'stat'e.

In' order to enable others skilled in the art to make and-use my invention, 1 will now proceed to describe its constructionand operation, reference being bad to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 is a vertical section of my improved ice-cream freezer.

Figure 2, a sectional plan on the line 1-2, fig. 1.

Figure 3, a plan view, and

Figure 4 a detached sectional view of part of the apparatus.

Similar letters refer to similar parts throughout the several views.

A is the exterior wooden vessel of the freezer, a the bottom of the same, and B a bar, extending acrossthe top of the vessel. To the top of this cross-bar, near one edge of the same, are secured plates 6 b, terminating in pins 0, adapted to holes in studsf, secured to the interior of the outer vessel A. It will be observed that on the oppositeedge of the cross-bar there is a recess for receiving-a pin, a, the latter serving to maintain the cross-bar in a proper horizontal position, while a latch-hook, t, fitting inthe pin, aids in keeping the crossbar down in its place on the top of the vessel A. A metal plate, D, of the form best observed on reference to fig, 3, is secured to the cross-bar B, and in this plate are formed, in the manner illustrated in fig. 4, bearings for the reception of the horizontal spindle E, on which is a'bevel-wheel, F, gearing into a wheel, G, the hub 72 of'wliich turns freely in the plate D, but cannot move vertically therein. In this hub of the wheel G is a square or other suitably formed recess for the reception of the upper end of the spindle i of the dasher H, which is constructed in a manner somewhat similar to that described in my patent of May 22, 1860, but has on one side three arms or projections j, to the middle one of which is hinged by a pin, m, a strip, is, of wood, the said strip being in contact with the upper and lower arms, but free to slide against the same when a vibratory movement is imparted to the strip through the inequalities of the interior of the vessel I, on the bottom of which-is a projection, 12, adapted to a step, g, on the bottom a of the vessel A. The vessel I isfurnished with a detachable cover, J, on which is a bevel-wheol, K, gearing into a handwheel, F, on the spindle E, the latter being furnished with a suitable handle, M, on turning'whicb the vessel I will revolve in one direction, and the dasher'H in the other. After the cream in the vessel I has been frozen by the revolving of the said vessel, amidst the ice contained in the outer vessel A, the latch-hook t is withdrawn from the pin w, the cross-bar B and appliances connected therewith are turned upwards on the pins e e, the lid J and dasher H are removed, and the frozen cream is withdrawn. The cross-bar B may be turned back without detaching it from the outer vessel wheneverit is desired to inspect the contents of the vessel I. When, however, the outer vessel is to be cleaned, the bar 13 may be detached by moving it laterally after turning it upwards so as to withdraw the pins 2 e from the studs ff.

One of the most important advantages of my invention is the facility with which the several parts can be taken apart, and readjusted, and made ready for operation; another important feature being the ease with which the vibrating strip K will accommodate itself to the inequalities of the vessel I, aud'thereby effectually scrape therefrom the frozen cream, and permit that which is in a fluid, unfrozen state to gain access to the side of the vessel. If necessary the strip K may be used in connection with the stationary dasher, arranged in a revolving can, or with a revolving dasher arranged in a stationary can.

' I claim as my invention, and desire to secure by Letters Patent 1. The cross-bar B, hinged to and retained on the vessel A, and carrying a wheel, G, having a recess adapted to receive the end of the dasher-spindle, substantially as described. I 2. The combination of the cross-bar B, its plate D, bevel-wheels G and F, and spindle E, and bevel-wheel K, on the cover of the vessel I.

3. The combination of the said cross-bar 13, its plate 6 b, and pins e, with the studs ff, on the vessel A.

4. The strip K, arranged to vibrate on a dasher, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
